Project Overview

The main objective of the VIATRA2 (VIsual Automated model TRAnsformations) framework is to provide a general-purpose support for the entire life-cycle of engineering model transformations including the specification, design, execution, validation and maintenance of transformations within and between various modeling languages and domains.

Target Application Domains

VIATRA2 primarily aims at designing model transformations to support the precise model-based systems development with the help of invisible formal methods. Invisible formal methods are hidden by automated model transformations projecting system models into various mathematical domains (and, preferably, vice versa). In this way, VIATRA2 nicely complements other model transformation tools within the GMT initiative.

The most traditional application area for VIATRA2 – started as early as 1998 – is to support the transformation-based dependability analysis of system models taken from various application areas (safety-critical and/or embedded systems, robust e-business applications, middleware, serviceoriented architecture) described using various modeling languages (BPM, UML, etc.) during a model-driven systems engineering process. Such a model (and transformation)-based dependability analysis typically also includes the verification & validation, the testing, the safety and security analysis as well as the early assessment non-functional characteristics (such as reliability, availability, responsiveness, throughput, etc.) of the system under design. In addition, model transformations for specification, design, deployment, optimization or code generation in traditional model-driven systems engineering are also focal areas for VIATRA2.

Standard conformance

We need to point out that the underlying modeling and transformation concepts of VIATRA2 are nonstandard.
